Product details
Overview
SA10C from Taiwan Semiconductor is a unidirectional 500W transient voltage suppressor (TVS) diode in DO-204AC (DO-15) package, with 11.1–13.6 V breakdown voltage (VBR), 10 V working stand-off voltage (VWM), and 18.8 V maximum clamping voltage (VC) at 27 A peak pulse current - designed for automotive-grade ESD and inductive load surge protection in power supply rails and signal lines.
For engineers reviewing the SA10C datasheet, SA10C pinout, SA10C application, or SA10C equivalent, key selection criteria include its AEC-Q101 qualification, sub-1 ps response time, <1 μA reverse leakage at 10 V, 175°C junction temperature rating, and compatibility with 10/1000 μs surge waveforms in automotive body electronics and lighting control modules.
Technical Context
The SA10C operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its specified VBR range (11.1–13.6 V at 1 mA test current), clamping transients to ≤18.8 V at 27 A. Its low dynamic impedance enables effective suppression of fast-rising EFT and ISO 7637-2 pulses without latch-up or thermal runaway.
Designed for surface-mount or through-hole assembly on 10×10 mm copper pads, it sustains 70 A non-repetitive forward surge (8.3 ms half-sine) and maintains stable performance across –55°C to +175°C operating junction temperature, meeting JESD201 Class 2 whisker resistance and RoHS/halogen-free requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse voltage before significant leakage; sets safe operating margin below VBR in 12 V automotive systems. |
| VBR @ IT=1 mA | 11.1–13.6 V - Breakdown threshold tolerance ensures reliable turn-on during transients while avoiding false triggering. |
| VC @ IPPM=27 A | 18.8 V - Clamped voltage under 10/1000 μs surge; limits downstream IC stress to safe levels in 12 V rail protection. |
| PPK | 500 W - Peak pulse power handling capacity per single 10/1000 μs event; supports ISO 16750-2 Pulse 5a/b immunity testing. |
| IR @ VWM | <1 μA - Ultra-low reverse leakage preserves battery life and avoids false wake-up in always-on vehicle modules. |
| TJMAX | +175°C - Enables placement near hot components (e.g., engine control units, LED drivers) without derating. |
| Response Time | <1.0 ps - Sub-picosecond avalanche initiation ensures suppression before sensitive logic or analog circuitry is damaged. |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with cathode band marking for unidirectional polarity; lead finish is pure tin, solderable per J-STD-002; weight ≈ 0.400 g.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Unidirectional, 10 V VWM, 11.1–12.3 V VBR, 1000 W rating, SMA package (smaller footprint, lower thermal mass) | Higher peak power but lower steady-state dissipation (1 W vs SA10C's 3 W); less suitable for sustained surge duty cycles | Prefer SMAJ10A where board space is constrained and surge events are infrequent; SA10C preferred for thermally demanding underhood locations. |
| 1.5KE10CA | Bidirectional, 10 V VWM, 11.1–12.2 V VBR, 1500 W rating, DO-201 package (larger than DO-15, higher IFSM) | Supports AC-coupled signals and bidirectional transients; not AEC-Q101 qualified; higher clamping voltage (21.2 V) | Select 1.5KE10CA only for non-automotive AC line or telecom interfaces; SA10C remains optimal for AEC-Q101-compliant unidirectional 12 V rail protection. |
Compared with SMAJ10A and 1.5KE10CA, the SA10C delivers AEC-Q101 validation, superior thermal robustness (3 W PD at TL=75°C), and tighter clamping (18.8 V) - making it the preferred choice for automotive power rail protection where reliability and junction temperature stability are critical.

FAQ
What is the exact breakdown voltage range for SA10C?
The SA10C has a minimum breakdown voltage (VBR) of 11.1 V and a maximum of 13.6 V, measured at 1 mA test current (IT). This range ensures consistent avalanche turn-on behavior across production lots while accommodating manufacturing tolerances - critical for predictable clamping in automotive 12 V systems where SA10C is commonly deployed.
Is SA10C unidirectional or bidirectional?
SA10C is a unidirectional TVS diode, indicated by the "C" suffix and confirmed by its cathode band marking and specification table entries limited to VBR(uni-directional). It conducts only during reverse overvoltage events and blocks forward current - making it ideal for DC power rail protection where polarity is fixed, unlike bidirectional variants (e.g., SA10CA) used in AC or data-line applications.
Does SA10C meet AEC-Q101 qualification?
Yes, SA10C meets AEC-Q101 qualification as documented in the SA Series datasheet (Version L2105), covering stress tests including temperature cycling, high-temperature reverse bias, and mechanical shock. This certification validates its suitability for automotive underhood and cabin applications - a key differentiator for SA10C versus generic industrial TVS diodes.
What is the maximum clamping voltage of SA10C at rated surge current?
The SA10C clamps to a maximum of 18.8 V at 27 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is guaranteed across temperature and lot variations, enabling system designers to verify that downstream components (e.g., 20 V-rated CAN transceivers) remain within safe operating voltage limits during ISO 7637-2 transient events.
What package type does SA10C use and what are its mounting requirements?
SA10C uses the DO-204AC (DO-15) axial package with pure tin-plated leads. For rated power dissipation, it must be mounted on 10 × 10 mm copper pads per terminal per JEDEC standards; this configuration supports its 3 W steady-state power rating at 75°C lead temperature and ensures reliable thermal performance in automotive environments where SA10C is routinely applied.
